Effect of lignocaine injection in carotid sinus on baroreceptor sensitivity during carotid endarterectomy Pippa G Al-Rawi, BSc, Dominique Sigaudo-Roussel, PhD, Michael E Gaunt, FRCS Journal of Vascular Surgery Volume 39, Issue 6, Pages 1288-1294 (June 2004) DOI: 10.1016/j.jvs.2004.02.005
Fig 1 Graphs show mean arterial blood pressure (MAP; mm Hg), r-r interval (R-R; ms), heart rate (HR; bpm), cardiac vagal tone (CVT; linear vagal scale), and carotid baroreceptor sensitivity (CBR; ms/mm Hg) responses to rub test 1 (before lignocaine injection) and rub test 2 (after lignocaine injection) in individual patients.

Fig 2 Graphic display of data obtained in one patient during carotid endarterectomy. Vertical lines demonstrate time of rub tests and injection of lignocaine. ABP, arterial blood pressure (systolic and diastolic shown); HR, heart rate; CVT, cardiac vagal tone; CBR, carotid baroreflex sensitivity.
